I volunteer in the foster system and in tutoring teens who live in group homes.
I know my geographic area isn’t typical of the nation. It is in no way urban, nor does it have the problems that urbanization brings. However; I don’t see a blanket of blame falling on young parents.
I see young parents having to grow up with their children and they do quite well. What I see, almost universally, is people who deny their poverty by escaping into drugs and sadly, choosing that escape over their children.
The majority of kids I work with have older parents.
